asterisk users - Oct 2012 - JAMI interface not working as expected

I have encountered a problem on an Ast 1.8 install where the AMI interface works
fine (I can login and issues command to AMI directly using telnet), but when I
use the JAMI/JAMA interface it fails.  Using curl (HTTP) I can login fine to the
JAMI, but as soon as I issue a second command it fails (despite saving session
cookies and extending the httptimeout on the Asterisk side).

The two JAMI commands (login, then ping) are issued within 3 seconds of one
another, so this should succeed (and it does on some other test systems).   I
read about this bug in Ast 1.6 but it should have been fixed by 1.8.  See here

This happens to be a FreePBX system...not sure if that makes a difference.?

Ideas?  Thanks!
